Which of the following is not involved in the processing of mRNA precursors in eukaryotic cells ?
Answers
RNA splicing. The third big RNA processing event that happens in your cells is RNA splicing. ... During splicing, the introns are revmoved from the pre-mRNA, and the exons are stuck together to form a mature mRNA that does not contain the intron sequences
Answer:
During the processing of mRNA precursors in eukaryotes, the splicing of exons does not take place.
Explanation:
The eukaryotic genes are consists of two regions namely coding and non-coding regions. Exons represent the coding regions and introns represent the non-coding regions. During transcription, both the regions are copied into the pre-mRNA transcript. This transcript is the initial one which is processed further. Few processes are involved in processing the pre-mRNA one of which is RNA splicing. During the splicing process, the non-coding regions, i.e., the introns are cut off. The remaining part is the exons which are joined together to make the final functional RNA.
Thus, splicing of exons does not take place. Instead, splicing of introns takes place in eukaryotes.
